A method and apparatus for assuring delivery of paid advertising to a user may involve asking a question about an advertisement or requiring data about the advertisement to be entered. In one embodiment, a human presence indicator, such as stylized letters, may be displayed during or after the presentation of an advertisement to be copied by a user to indicate presence during the advertisement. When the challenge relating to ad viewing is correctly answered, a value associated with viewing the ad may be credited to a user account, either locally or at a clearinghouse or other repository.
Legal claims defining the scope of protection, as filed with the USPTO.
1. A method of verifying and compensating for consumption of advertising at an electronic device comprising: providing a displayable data; taking a cryptographic measure of at least a portion of the displayable data to create a first measurement of the displayable data; downloading the displayable data; downloading a packet comprising the first measurement corresponding to the at least a portion of the displayable data and a value packet; loading the displayable data into a display memory, wherein data in the display memory is presented on a display of the electronic device; presenting the displayable data on the display of the electronic device; taking a second cryptographic measurement of the at least a portion of the displayable data while the displayable data is in the display memory and being displayed to create a second measurement; comparing the first measurement to the second measurement; processing the value packet in response to determining that the first and second measurement match; and wherein processing the value packet comprises adding a value amount indicated in the value packet to a locally maintained stored value account.
2. The method of claim 1 , wherein the first measurement is a hash of at least a portion of the displayable data.
3. The method of claim 1 , wherein the first measurement comprises a digital watermark of the displayable data.
4. The method of claim 1 , wherein downloading the packet comprises downloading the packet comprising the first measurement corresponding to the displayable data, the value packet, and metadata indicating a portion of the displayable data to which the first measurement pertains.
5. The method of claim 4 , wherein loading the displayable data into the display memory comprises loading the displayable data into the display memory and providing the metadata to a security module for processing the display memory.
6. The method of claim 4 , wherein processing the displayable data comprises reading the portion of the displayable data identified by the metadata.
7. The method of claim 1 , further comprising: using, at a security module, a bus master function capable of accessing and controlling the system bus to read the display data in the display memory, wherein processing the displayable data comprises directly reading the displayable data at the security module without using a main processor of the electronic device while the displayable data is loaded in the display memory so that displayable data is presented on the screen of the electronic device.
8. The method of claim 1 , wherein the displayable data is an advertisement.
9. The method of claim 1 , wherein the displayable data is a menu bar.
10. The method of claim 1 , wherein the downloading the packet comprises downloading the packet and cryptographically authenticating and decrypting the packet using a key or keys stored in a security module of the electronic device.
